Cybex Sirona G I-Size Car Seat

Say hello to rear-facing travel with the CYBEX Sirona G i-Size car seat, with up to 50% higher safety levels for your child, compared to the same seat forward-facing in a frontal crash.*​

​The Innovative 360° rotation technology (when used with modular Base G ISOFIX base, sold separately) makes on and off-boarding so much simpler for parents as the child is placed in a much more-manageable position. It also makes it easier to make the choice to switch to forward-facing travel when your little one is older, after 15 months (76cm). ​

​Once they’re onboard, the all-round ventilation system with special mesh fabric which is six times more breathable** will keep them cool and comfortable whatever the weather. ​

A cleverly integrated Linear Side-Impact Protection System gives streamlined, reinforced protection in the event of a side collision. As part of the Modular G Line car seat family, the Base G ISOFIX base, also used for the Cloud G i-Size, fits the Sirona G i-Size to use going forward till approx. 4 years old (Base G sold separately).​
